action as certain in a greater or
less degree, I have strengthened
in every reasonable way the
foundations of the works at
the particular points referred
to, and I have raised the flank
revetments to such a height that
I believe they may be looked
upon as secure from any con-
-tingency of accident arising
from the meeting of the two
streams.
The whole of the works
attached to the inlet and which
I have described under the
division C, are protected by
aprons [as before described, struck through] consist-
-ing of piles driven 20 feet deep
in close lines at distances (as
represented in the plan) from the
foot of the walls in the case of
the revetment, and in advance
of the front and rear in that
of the inlet; the intermediate
space being filled with box
work and river stone covered
with sleepers well clamped
down to the piling. The aprons
on all occasions slope[ing, struck through] out-
-wards from the work to a per-
-pendicular depth of 18 inches,
the terminations of the wings
on the upstream side towards
the torrent are well protected
by open piling connected by
transverse ties or transoms.
D Under this letter we
arrive at the regulating bridge;
its connection with the dam
and inlet; and the uses made
of its foundations for the purposes
of under drainage.
